  • In this paper, a new design of the sprinkler branch outlet for fire-extinguishing purposes is presented together with its manufacturing process. The conventional three-piece design is improved by a new one-piece design with the help of the manufacturing technology of cold forging. The forging process is simulated and optimized by the rigid-plastic finite element method and the design tryouts are thus minimized. It has been shown through its applications that the presented system is much more economical and structurally stronger.
